IMPROVEMENT IN COOKING-STOVES.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, L. W. IIARwocD, of Troy, oi' Rensselaer county, intho'Stete of New York, have inventcdcertnn new and useful improvementsin Cooking-Stoves; and I do hereby declare that the following is a fullund exact description thereof, reference being had to the accompanyingdrawings, making part of this application.

My invention relates to that kind of stovein which a. suspended {ire-boxis employed; that -is to say, e store in which the oven-spaces extendalong under the lire, und up in front of und behind it, es for instancein what is known :is the Stewart Stove. Previous to my invention it hasbeen customary to construct this kind of stove with e. closed frontendhanging suspended fire-box, und so as to leave beneath the grate e.comparatively small space, (shallow,) or aslrpit, into which theashesfrom the grate could descend, and from which they had to be removed.

The construction and operation of this kind of stove are well known tothe manufacturer and user. It has been found in' practice that severalvery serious objections exist in this mode of construction of a. stove,among which nie-y be mentioned the objection of having the space infront of the lire-chamber closed entirely, und my invention has for itsobject to overcome this objectionable feature in this kind of stove,(having a. hanging or suspended iire-box,) end provide u stove which,while it has the suspended hre-box, shell possess the advan tage ofhaving un open front to the fire-chamber space, in combination with theother well-known features in this class of stoves. And to these ends myinvention consists in the employment, in combination with e. dump ing ormovable grote and oven, extending beneath and up behind theiire-chomber, and suitable ash-pit, whereby the ashes und cinders overthe grntelbors mcy be readily dumped or sha-ken down into a. Space belowthe grate-bers suiciently large to avoid the liability of frequentlyclogging up, and from which they een be readily removed, of anopen-front fire-space, as will be more fully explained presently.

To enable those skilled in thenrt to make and usc my invention, I willproceed to describe it more fully, referring by letters to theaccompanying drawings, in which- Figure I is un elevation or side View,and

Figure 2 o. vertical section on line a: x, fig. l, of u cookingstoveembodying my invention.

In the different figures the seme letters of reference denote the likeparts.

A is the oven-space; B the fire-space; C the grate; I) the ash-pan ordrawer, and F the door to the lireehumber. The stove represented isabout similar to the well-known three-flue stove of this class, with myimprovement embraced therein. As I have said before, previous to myinvention this Aclass of stoves hns been constructed with the space infront of the hre-chamber entirely closed, und in avoiding thisobjectionable feature I construct my stove with un opcnfront ire-spuce,not clearly represented in the drawing, oapeble of being closed by a.dooi' or doors, which though not shown I propose to provide in themanufacture, the object of which is readily perceived. For instance,when it is desirable to have all the heut from the {ire-chamber radiatedinwardly to the oven, the doors ure closed, und when any particularamount of air is needed, the door or doors can be opened to any extentdesired, or the door or doors -may be entirely opened, allowing all theheet from the-front ofthe lire-chamber to radiate outward, whereby I amenabled to roest as perfectly as before e grated front or on open{ironie-cet The grote is so constructed und arranged that it con beoscillated or turned on zt longitudinal exis for the purpose of shakingout the ashes, and, when desired, dumping the contents of the fire-spaceB into the ashpit D, which lutter should be mede oi' sufficient depth toadmit of the readily dumping of the' fire, I propose to use in the seidcsh-pit e sliding drawer or ushpun, E, which may have a suite-blehandle,f, and which can be withdrawn and replaced endwise when theVvdoor g is open for the purpose of carrying away the ashes und cinders,by menus of which the ashes een be removed without causing any dust crdirt in the room occupied by the stovci It will be understood thatalthough I have shown a particular kind of stove, with three lues,

etc., my invention een be used equally es well in any other" stove inwhich e suspended fire=box isused, and although I propose to employ theash-pon E as very desirable, it muy be omitted withoutdetrccting fromthe mum advantage of my invention, which rests in the idee of having anopen front to the tire-chamber space,

the grate movable, and the space beneath the grate suieient to admit ofthe necessary motion todump and readily shake out the ashes and cinders,and allow always a free draught to the fire. Of course various otherforms of grate may be hung,'to move dii'erently from that shown, withoutdeparting from the spirit of my invention.

I am aware that neither the suspended fire-box, ash-pan,ashpit, nordumping-grate is new, and do not claim as of my invention any of thesespecialties, but what I do claim as new, and desire to secure byYLetters Patent, is- I l The suspended ire-box, having an open frontspace, andl with the oven-space extending beneath and up behind it, incombination with the dumping-grate and ash-pit, the whole .arranged tooperate .as specified for the purpose set forth. y I* In testimonywhereof I have hereunto set my hand and seal this third day of May,1867.
